SLIDING MOLDBOARD FOR CABINETS.

Application -led August 14, 1922.

To all 10h-0m t may] concer/a.' l v Be it known that I, HARRY A. HALL, a citi- 'zen of theUnited States, residing atllewcastle, in the county of Henry and Sta-te of Indiana, have invented new and useful lmprovements in Sliding Moldboards for C'abinets, of which the following is a specification.

Slidable mold-boards for kitchen cabinets have been made as shown in my Patent No. 1,408,938, issued February 1st, 1922, wherein a positive lock was provided to hold the mold-board from sliding when drawn out :i maximum distance, but not-holding it a distance less than the maximum; and an object of this invention', is to provide means for locking the mold-board at practically any position thereof within the range of its slid'- ing movement. Another object. is to mount the inner edge of the mold-board between roller-bearings to keep it from binding when slidingly moved; and a. further object is to provide resilient means for taking up lost motion of the mold-board in all of its positions, to hold it steady| and free from rattling, all without interfering with its free dom of adjustment.

I accomplish the above, and other objects which will hereinafter appear, by the mechanisni illustrated in the accompanying drawing, in which- Fig. 1, is a vertical section of the moldboard and its associated co-operative parts, showing my invention, the section being on the line 1-1 of Fig. 2. F ig. 2 is a vertical section of same on the line 2 2 of Fig. 1, and Fig. 3 is a fragment in underside plan view of the mold-board.

Like characters of reference indicate like parts in the several views of the drawing.

In the drawing, 4 indicates the main body or cabinet base whit-h, at its upper portion, is provided with frame members 5, in which pins 6 are seated in' vertical pairs` forming guides for corresponding track-bars 7. These are each suppoited on a plurality of springs 8, which enter sockets in the under sides of the track-bars and bear upon the members 5.

Supported at a suitable distance above the cabinet base 4, by end-plates 9, 9, is a cabinet superstructure 10, of any usual or suitable construction. A. mold-board 11, appropriately formed of a wooden-frame and core and incasing metal cover 12, is slidingly assembled between the base l and superstruc Serial No. 581,621.

ture 10. The bottom 13 of the superstructure has depending roller housings secured to the underside near each end of the cabinet, with a roller 15 mounted in each housing, preferably of lignum vitae, or similar strong material that will not mar the metal top by rolling over it.

Secured to the underside of the moldboard near each of its ends is a bar 16, and secured to the underside of each bar near the inner ends thereof isa inet-al'housing in which a roller 15 is mounted. The roller bears against and rolls upon the adjacent track-bar 7.

Nailed to the underside of 'the bar 16 is wedge-block 18, turned with its broad end to the front to Contact the front wall of the base and limit the outward movementof the mold-board under ordinary conditions of use, butit does not prevent the clearance of the wedge by further lifting of the front of a mold-board. l l

To lock the mold-board at a large number of positions so a person using it may lean against it without its sliding, I fastena vertical plate 20 in a fixed manner to the inside front of the base 1, and'provide a longitudinal series of indents on the adjacentbar 16, in respective ones of which the end of plate 20 enters, depending upon the position of the mold-board. These indents may be conveniently formed in practice by .nailing a strip 22 of corrugated metal longitudinally of the bar 16, in the manner shown in Figs. l 21nd 3.' v y The operation of my invention is as follows: `When the mold-board is in the position shown, or between that and full closed position, and until the lower rollers pass to the front ofthe upper ones, the springsB, acting through the track-bar 7, press the back portion of the mold-board up, and the upper rollers, acting as fulcrums, force'tlie l'ront portion of the inold-board down into locking engagement of the corrugated strips 22 with the plates 20, and the spring-pressed track-bars cause the mold-board to be always closely held between the upper and the lower rollers, thereby preventing all looseness and the rattling of the board in use.

When it is desired to move the moldboard either in or out, it is freed from the plates 2O by lifting up on the front of the board. The board yswings against the top rollers ,as ulcrums, causing the lower rollers by rolling contact to push the trackbars down far enough to permit the adjustment but never far enough to be free from the' resilientx action of the track-bar in the preventing of* lost motion of the board.

Having thus fully described my invention, what I claim as new and wish vto secure by Letters Patent of the United States, 'is--Y 1. In a kitchen cabinet, a base, a superstructure, a mold-board on the base slidable in and out under the superstructure, means for holding the mold-board against sliding adjustment either in or out when 4at any position in its normal range of movement,

v the means for holding the mold-board against such sliding adjustment consisting of; parts fixed tothe mold-board and to the cabinet respectively without motion of that part` relative to the mold-board or to the cabinet member to which the part is fixed, track bars, resilient means for normally moving the track-bars toward the moldboard, and bearings between the mold-board and the superstructure and between the mold-board and the track-bars.

2. In a kitchen cabinet, a base, a superstructure, a mold-board on thefbase slidable in and out under the superstructure, means comprising' a movable part movable with the mold-,board but immovable relative to the mold-board, for holding the mold-board against sliding adjustment either yin or out when at any position in its normal range of movement, the position being variable at wil-l by yappropriately moving the moldboard and said parts liXed thereto, track bars, resilient means for normally moving the track-bars toward the mold-board, and bearings between the mold-board and the superstructure and between the mold-board and the track-bars.

` 3l In a kitchenvcab-inet, a base, a superstructure, a mold-board on the base slidable inv and out under the superstructure, movable track-barsof. rigid material supporting the inner edge of the mold-board, resilient means supporting the track-bars and slidingly forcing them toward the molidboard to take up lthe looseness of the latter and to prevent the rattle oi' parts and devices to concentrate the load of the board at bearing points on the track-bars.

4;. In a kitchen cabinet, a base, a superstructure, a mold-board on the base slidable in and out under the superstructure, movable track-bars ot rigid material supporting the inner edge of the mold-board, springs forcing the track-bars toward the mold-board, and anti-friction devices above and below the mold-board toease its sliding movement under the pressure of the springs and to concentrate the load of' the board at bearing points on the track-bars.

`5. In a kitchen cabinet, a base, a superstructure, a mold-board on thebase slidable in and out under the superstructure,v rollerbearings between the superstructure and mold-board fixed to the superstructure, roller-bearings under the mold-board fixed to the mold-board, movable track-bars'under the mold-board 'for the last 'rollers to roll upon `and springs to press the 'trackbars toward the mold-board. A

6. In a kitchen cabinet, a base, a superstructure, a mold-board` on the ybase slidable in and out under the superstructure, rollerbearings between the superstructure and mold-board tixed to ythe siuperstructure, roller-bearings under the mold-board fixed tothemold-board, movable track-bars .under the mold-board for-the last rollers to roll upon, springs to press the track-bars toward the mold-board, and means for holding the mold-board against slidingk adjustment at any position of its range in use, Signed at Newcastle,` Indiana, this the 45th day of August, 1922.
